流动注射分析法同时测定水中挥发酚及氰化物

Simultaneous Determination of Volatile Phenol and Cyanide in Water by Flow Injection Analysis

本文利用SKALAR SAN++连续流动分析仪对水中挥发酚及氰化物进行同时测定。实验结果表明,该方法对于挥发酚和氰化物,分别在0~0.200 mg/L和0~0.100 mg/L范围具有良好的线性关系,相关系数分别达到0.9999及0.9998;方法检出限分别为0.0007 mg/L及0.001 mg/L。实际水样加标回收率分别为95.0%~102%及96.4%~106%。该方法具有测试准确、分析快速,操作便捷,试剂消耗小等优点,适合于水质监测批量样品的测定分析。

In this work,SKALAR SAN++continuous flow analysis was developed for the volatile phenol and cyanide in water.The results showed that the good linear relationships were obtained when the concentration range of 0~0.200 mg/L for volatile phenol and concentration range of 0~0.100 mg/L for the cyanide,and with correlation coefficient of 0.9999 and 0.9998,respectively.The detection limits were 0.0007 mg/L(volatile phenol)and 0.001 mg/L(cyanide),respectively.The recovery efficiency of water samples is 95.0%~102%and 96.4%~106%,respectively.The method has the advantages of accuracy,rapid analysis,convenient operation and low reagent consumption,which is suitable for analysis of batch water samples for the water quality monitoring.
